Did you even try to understand the reasoning behind the changes before jumping to conclusions? Sometimes updates take some getting used to, but they often have a purpose.
Actually read the change log, it's a major performance overhaul and sets the stage for some big features down the line. This update is laying groundwork, not meant to be flashy.
totally feel you. I just got done reinstalling an older version bc the new update killed the game's UI. seems like a slap in the face for loyal players.
